What the Odds Say
Marcus McGhee enters this Benardo Sopaj vs. Marcus McGhee matchup as the clear consensus favorite across all 15 books listed. His moneyline ranges from -141 (Caesars Sportsbook) to -196 (Grosvenor), a wider spread than you typically see at this level. Sopaj is priced as a live underdog ranging from +104 (Grosvenor) to +133 (Bovada). The fight is scheduled for Saturday, October 3 at 5:00 PM PDT, giving bettors a full week to shop lines before the opening bell.
At the consensus range of roughly -149 to -154, the market puts McGhee's implied win probability around 60%. That is not a blowout-level favorite situation, and the books are treating Sopaj as a legitimate threat.

Converting the moneylines into implied probabilities gives you a clearer picture of how oddsmakers view this fight. You can run these numbers yourself using the Odds Converter to flip between American, decimal, and fractional formats.
Marcus McGhee implied probability range:
- Caesars Sportsbook (-141): approximately 58.5%
- BetOnline.ag (-143): approximately 58.9%
- BetMGM (-149): approximately 59.8%
- NordicBet (-156): approximately 60.9%
- Grosvenor (-196): approximately 66.2%
Benardo Sopaj implied probability range:
- Grosvenor (+104): approximately 49.0%
- BetOnline.ag (+122): approximately 45.0%
- BetMGM (+125): approximately 44.4%
- Bovada (+133): approximately 42.9%
The Grosvenor numbers are worth flagging on both sides. Their -196 on McGhee is a significant outlier compared to the rest of the market sitting between -141 and -156. If you are considering a McGhee bet, Grosvenor is the book to avoid. Conversely, their +104 on Sopaj implies nearly a coin flip, which is far more generous than the rest of the market. That kind of discrepancy signals a potential inefficiency worth exploring with the Arbitrage Calculator.
Line Shopping Matters Here
The spread between the best and worst prices on both sides of this fight is unusually wide.
For Sopaj backers, the difference between +104 (Grosvenor) and +133 (Bovada) is meaningful. On a $100 bet, that is $29 in additional payout just by having accounts at multiple books. For McGhee bettors, the gap between -141 and -196 is even more significant. The Grosvenor price requires you to risk substantially more for the same outcome you could get at a better number elsewhere.
The Total: One Book Leaning Toward a Longer Fight
Only one book is currently posting a total for this fight. 1xBet has set it at 2.5 rounds, with the Over priced at -182 and the Under at +136. That steep lean toward the Over suggests the book expects this fight to go past 2.5 rounds. With no competing line to compare against, treat this number with caution. A single book's total is not a consensus.
Key Factors to Watch Before Fight Night
Line Movement
The spread between books is notable now, but what matters heading into Saturday is whether sharp money or late public action compresses that range or pushes McGhee's price higher across the board. If McGhee moves past -160 at multiple books, that signals genuine market confidence. If books drift toward the Sopaj side, something may have shifted in the matchup narrative. Tools like Steam Moves can help you spot when sharp money is hitting a side.
Finish Rate and Style
MMA underdog bets carry more variance than other sports. A single punch or submission can end a fight at any moment. Sopaj's pricing at +133 on Bovada reflects a real finishing threat. Each fighter's history of quick finishes matters as much as their overall record when handicapping this spot.
Late Scratches and Weigh-In Results
Weigh-ins typically take place the day before the fight. A missed weight or difficult cut can shift lines quickly. Monitor the card on October 2, because weigh-in news often creates short windows of value before books adjust.
With a week until fight night and notable price differences already visible across books, Sopaj vs. McGhee is a matchup worth tracking closely before you commit to either side.
